T at who/It it ntrty concern:

Be it known that I, EUGENE E. BARTHOLO- Mnw, residing at Cleveland, in the county of Cuyahoga and State of Ohio, have invented a certain new and useful Improvement in Illachines for Slotting the Ends ofBlanks for Barrels, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings.

My invention relates to machines for slotting the ends of blanks for barrels in order to give the proper bilge to the completed barrel, and has for its object the construction of a machine of this character which shall be effectual in operation and simple and economical in construction.

Generally speaking, the invention may be defined as consisting of the combinations of elements embodied in the claims hereto annexed.

Referring to the drawings, Figure 1 represents a plan view of a machine embodying my invention. Fig. 2 represents a side elevation of the machine shown in Fig. 1. Fig. 3 is a perspective diagrammatic view representing a form of mechanism for operating the feeding device for the staves or blanks. Fig. dis a central transverse sectional view of the machine shown in Fig. 1. Fig; 5 is adetail view showing the drum which operates the saws and the actuating mechanism for said drum. Fig. 6 represents a portion ofa blank or stave, showing the same after it has been operated upon by my machine.

All veneer barrels with which I am familiar and which are actually on the market are either formed as a cylinder made of one or more blanks or staves of veneer with no bilge therein or are formed of a plurality of narrow individual veneer staves. In order to give the necessary amount of bilge to a barrel made of one or more wide staves, it is necessary to kerf or slot the ends of such staves or blanks, whereby such ends may be contracted when the staves or blanks are formed up into the barrel. The machine which forms the subject matter of this application is designed to slot or kerf the ends of such blanks or staves in a most effective and simple manner.

My machine consists generally of three partsviz., aframe or support for the material to be operated upon, mechanism for cutting gores or kerfs in the ends of such material, and means for advancing or feeding the material along the supporting-frame between the cutting or slotting operations.

The frame or support is designated by the numeral 1, and consists generally of upright posts 2, lower sills 3, upper sills 4;, and end sills 5. The upper surface of the supportingframe is provided with slats 6, on which the staves or blanks are supported. Projecting above the slats and secured to the side sills t are the longitudinal strips 7, the distance between said strips corresponding to the desired length of the stave or blank from end to end of the barrel.

In order to feed the material along the bed or frame, a carriage 8 is provided, said carriage consisting of apair of longitudinal rails 9, resting in guides 10 and connected by crossbraces 11. Below said carriage is the rack 12, which is suitably secured to the carriage, as by means of pins 13 connecting the same to the cross-braces. The material may be clamped to the carriage in any suitable manner.

The carriage with the blanks or staves thereon is advanced or fed along the frame by means of suitable mechanism, as by means of the levers shown in Figs. 1, 2, and 3. A lever 1% is pivoted at 15 to any convenient portion of the frameas, for instance, one of the lower sills 3. Connected to said lever 14:

is a link 16. This link is connected at its opposite end to the lever 17, which is pivoted at 18 to any convenient part 19 of the frame. The end of the lever 17 opposite the link 16 is suitably connected to an upright lever 20, which is pivoted at.2l to a suitable support 22. The upper end of the lever 20 engages teeth 220 of the rack 12. As will be readily seen, by operating the lever lt the rack and carriage and the staves or blanks thereon are fed or advanced along the frame. A detentpawl 23 engages the rack to prevent the same from being carried backward by means of the weight 24 and rope 25, secured to said rack, the rope passing over the pulley 26. (See Fig. 2.) At the opposite sides of the frame there is provided a bed-plate 27, each of said bed-plates having formed therein a V-shaped slot 28. These slots, as will appear from Fig. 1, are staggered or out of alinement for a purpose to be hereinafter described.

The mechanism for slotting the staves or blanks consists of two oppositely-mounted cutting members 29, said members being prefl erably circular saws provided with lateral tongues or teeth 30 projecting therefrom, said tongues or teeth increasing in length from the circumference to the center of the saw, as shown in my application, Serial No. 213,610, liled June 22, 190%. These saws are supported at the ends of mandrels 31 32, the mandrel 32 being somewhat longer than the mandrel 31, the parts being so arranged as to bring the saws opposite the slots 28. These saws are normally supported outside of the frame 1 and out of contact with the staves or blanks which are supported on said frame. In order to bring these saws into and out of contact with the material to be operated upon, I employ the following construction: The mandrels 32 and 31 are respectively supported in bearings 33 on a carriage 3st 3% and are each provided with a drive-pulley 35. The carriages are slidably supported by means of sleeves 36 on rods 37, said rods being supported in bearings 38 and 39, the latter bearings being located adjacent to the sills 4L. These rods may be threaded adjacent to the bearings 39 to receive each an adjusting-nut 4.0, which, engaging the carriage or the adjacent sleeve 36, will limit the movement of the carriage and of the saws and the depth of gore or slot which said saws will form in the staves or blanks.

The inner and outer ends of the carriages are flexibly connected to a drum a1, which is conveniently located below the middle of the frame. A pair of idle pulleys a2 and 43 are supported above the drum. A rope or other flexible connection it is secured to the inner end of the carriage 3a, whence it passes over the pulley 43, then beneath said pulley and around the d rum &1, the other end of said rope or connection passing around an idle pulley 45 and being secured to the outer end of the carriage 34:. A similar rope or flexible connection :6 is secured to the inner end of the carriage 34:, passes over the idle pulley 4:2 and directly around the drum 4L1, passing around said drum in the same direction as the rope or connection a thence passes around the idle pulley 45 and is secured to the outer end of the carriage 31. By the arrangement just described it will be apparent that the rotation of the drum i1 will cause both the carriages and the saws supported thereby to be simultaneously advanced toward or retracted from the slots 28 and will enable said saws to simultaneously slot or gore the material supported above said slots. 27 constitute supporting-surfaces for the ends of the blank. Owing to the thinness of the blank, such blank being ordinarily made of veneer of one-fourth inch thickness, the provision of some such support for the ends of the blank is necessary in order to prevent the blank from being cracked or otherwise mutilated by the cutting movement of the saws.

The bed-plates A convenient manner of operating said drum is shown in Fig. 5, wherein 4:60 designates one of the vertical posts forming part of the frame which supports the carriage 3e, 47 an operating-lever pivoted at 48 to a suitable support carried by said frame, L9 a link connected to said lever 47, and 50 a crank connected to the drum 41. It will be evident that by operating the lever 47 the drum 41 may be rotated to throw the saws into and out of engagement with the blank or stave 51 to cut the slots or gores 52 therein.

\Vhile 1 have shown as the cutting members saws which are adapted to form V-shaped gores or slots in the blanks or staves, it will be apparent that the proper bilge may be given to the barrel by other means, as by forming a plurality of plain kerfs in the ends of the blank, and I do not propose to limit my invention to the V-shaped gores or slots except as such limitations may be included in the claims hereto annexed.

Vihile I have also described my invention as specially applicable to cutting barrel blanks or stavcs, it may be employed for cutting other material as well, and while I have necessarily shown numerous details in the embodiment of my invention herein disclosed 1 do not propose to be limited to such details except as they may be included in the claims hereto annexed or rendered necessary by the prior state of the art.
